The purpose of this study is to analyze the efficiency of resident companies in port hinterland logistics that are currently operating. The subjects of the efficiency analysis include 13 logistics hinterland resident companies in Incheon Port and Busan Port. Investment amounts, area, and number of employees were selected as input variables, and volume and sales amounts were selected as output variables. As for the efficiency analysis methods, traditional CCR and BCC models were applied. To overcome the limits of these models, a super-efficiency model and a Super-SBM model were also applied. According to the super-efficiency model analysis, the mean was 0.777 and the standard deviation was 0.54, indicating an approximate 33% difference of efficiency among the companies. According to the Super-SBM model analysis, the mean was 0.649 and the standard deviation was 0.489. When considering residuals in the super-efficiency model, the average efficiency score among the companies decreased by approximately 13%. This means that the efficiency score decrease of DMU, where non-radial residuals exist at about 18% on average. Examining the inefficiency of the inputs, the inefficiency of the number of employees turned out to be largest at -45%, compared to 'area' at -33% and 'investment amount' at -33%.

In this paper, we implement an m-LIS(Mobile-Logistics Information System) for an effective logistics management in consideration of logistics process and work environment. The m-LIS could perform the entire business process every minute and promote the work efficiency by tying up with ERP and POS system. Moreover, this system could enhance the management level of service and supply chain. Due to the reason that the existing logistics business was not computerized and automated, most of operation was accomplished by means of workers experience and convention. This problem brought about both the ineffective management and logistics quality deterioration by weakening the control power of the logistics site. In order to solve this problem, we put focus on providing the real-time operation monitoring environment on the spot, the satisfaction of the efficiency on the spot, and the optimized system by building up the logistics information system. Furthermore, we attest that the new logistics system could properly cope with the increase of the quantity of goods transported owing to stable logistics information support and the market expansion and growth caused by the firm interface between the new ERP and its related system.

반도체 제조시설의 효율성을 위해 대부분의 현장에서는 물류 자동화 시스템 (AMHS, Automated Material Handling System)을 도입하여 운영하고 있다. OHT(Overhead Hoist Transfer)는 반도체 공정에서 주로 활용되는 Monorail 컨베이어 형태의 자동 반송 시스템의 일종으로 작업물을 들고 제조라인 위에 설치된 레일을 따라 자율적으로 이동하는 방식으로 운영된다. 도체 물류 시스템의 계층적인 구조적 특징과 고가의 재료를 다루고, 외부유출이 어려운 실제 공정 현장, 실험 환경의 시간, 공간적 구축 등의 현실적 특징 때문에 반도체 제조 공정의 자동화 물류시스템에 대한 모델링 및 시뮬레이션을 통한 연구의 필요성이 대두되고 있다. 본 논문에서는 OHT를 효율적으로 제어하기 위해 DEVS(Discrete Event System Specifications) 형식론을 기반으로 OHT 시스템 모델링 및 시뮬레이션 설계 방법을 제안한다. 이를 위해 반도체 제조 시스템의 전반적인 물류 과정에 대해 분석하고, DEVS 형식론에 대해 연구하며, 이를 바탕으로 반도체 물류 시스템을 위한 모델링 및 시뮬레이션을 설계하였으면, 실험을 통해 제안된 모델리 반도체 물류 시스템 시뮬레이션을 수행할 수 있음을 보인다.

The increase of international and domestic trade according to global industrialization and economic growth has raised the national logistic cost in connection with physical distribution of articles. In order to reduce these costs and rise up national industrial competitiveness, Korea has also tried to improve the efficiency of logistics with various methods as advanced countries did. Especially, Korea government has decided standard dimension of pallets with T11 ($1100{\times}1100mm$) on the basis of unit load system in early 2000s, and certification program for logistics equipments has been operated to keep up the compatibility for the equipments and packaging with modulation of T11. Consequently, this certification program has contributed to extend standardization for logistics and to grow up 3 party logistics, but compared with advanced countries, the rate of national logistics cost to GDP (gross domestic product) still shows about 3% gap as demands for certification have been decreased in the recent. In this study, therefore, we proposed the development of logistics certification system based on social needs as a policy device to activate logistic industry as well as improve the efficiency of national logistics after we had analyzed all of certification programs for logistics being run in Korea. Namely, the first is the development of certification project for Northeast Asia's logistics corresponding to necessity for applying returnable transport system according to increasing the amount of trade between Northeast Asia's countries. The second is the development of certification project for safe transportation of packaging corresponding to costumer's needs for safe transit according to the growth of electronic commerce and the increase of global distribution.

국제 무역의 활성화와, 운송수단의 기술적 발전은 국가 간 교역을 증대시키게 되었다. 특히 해상 무역 물동량의 증가는 국제항을 다양한 재화 및 여객 소통의 중심으로 만들었고, 경제적 관문으로써의 중요성이 높아지고 있으며 점차 국가 주요 기반 시설로 자리 잡고 있다. 즉, 원활한 교역을 위한 물류 효율화 달성과 안전한 항만 운영을 위한 보안 제도 강화의 필요성이 증대됨에 따라, 이를 효과적으로 관리 유지할 필요가 있게 되었다. 이에 본 논문은 자동화 고부가가치 서비스가 가능한 정보 중심의 u-Port(Ubiquitous Port)를 국가 전략적 차원에서 육성한 대한민국 사례를 기반으로 효율적인 항만물류를 위한 기반 시스템으로 활용될 수 있도록 해운물류표준화 기구인 IMO(International Maritime Organization)에 선진 사례로 소개하고 활용할 수 있는 방안을 제시하고자 한다. u-Port는 수출입 화물 관리가 용이하며 항만 보안을 강화하는 등 항만 업무 효율화를 제공할 수 있다는 장점으로 향후 개발도상국 또는 후진국의 항만 업무 생산성 및 투명성을 높일 수 있는 기반을 지원할 수 있을 것이다.

Container terminals can maximize operational efficiency when appropriate berths (lengths) and yard capacity are secured. However, some container ports, such as Busan New Port, are separated and operated individually, which limits the efficiency of logistics. In this study, it was analyzed that the efficiency of the overall terminal operation (logistics) can be greatly improved when the yard co-petition area is used for two adjacent container terminals.

This study is to understand basic knowledge on e-logistics through the analysis of third party logistics(3PL) as well as fourth party logistics(4PL) and to suggest some activation plans of e-logistics of information era to get competition in the field of international logistics. Compared with advanced countries, Korean companies has not activated 3PL logistics as Korean companies are not inclined to open their business information to others and they didn't recognize the importance of logistics. As the business environments are worsening little by little, there has been greater concerns for e-logistics as a way of focusing on the core-business. Most of Korean companies has outsourced simple and limited scope of 3PL and 4PL services with 1st level of logistics outsourcing. To activate e-logistics, Korean government and private enterprises have to pursue the following strategies. First, Korean government should change the present laws preventing the enterprises specialized in 3PL from doing business and should pursue logistics information and standardization. Also the government needs to support 3PL companies. Second, private companies do their best to retain and develope factors of logistics resources professional and to develope the latest technology. 3PL providers have pursue effective logistics strategies and to invest capitals for the information technology.
